No they are supposed to generate -nan.  If it does not then there is a bug
somewhere else.

Really you should report this to Apple since it is a bug in their snprintf
implementation.
Here is the code:
        // FIXME: Support floating-point formatting in sanitizer_common's
        //        printf, and stop using snprintf here.
        char Buffer[32];
        snprintf(Buffer, sizeof(Buffer), "%Lg", (long double)A.Float);
        Printf("%s", Buffer);
